Java Script functions Added to my page.

I need some functions added to my page designed for custom lettering. This is a custom built page. This will require knowledge in woocommerce ,Java Script,CSS and WordPress. I am not looking for a "team" I want one solo person with the skills I need. Must have incredible communication skills and able to speak clear english and able to talk live to me. I am not good typing and prefer to just talk skype or messenger here . Job details below. On my lettering page at [login to view URL] I need to add on that page a button that says (Ad More Lettering.) "purpose to clear current lettering and start a new text rendering. It will also Need (Add Qty Button. ) Purpose is to allow them to add more than one to the cart on that page. On this same page. I need the java script code added that will uncheck metal flake when Gradient is clicked. I also need the price to change when a customer has selected metal flake then they changed there mind and go back with a standard color. The price should go back to default. Metallic flake and Gradient should add 50 percent more. There might be a few other glitches where the price changes to default or charges a tad to much. I need in the css for the outline and shadow feature to be moved below the color selection. See that tab. I would like a few buttons to add up sells to the cart on the same page. I have a few up sells i would like to add to the page that are clickable and willl add to the cart if chosen. Such as Dome My Lettering Which will charge 120 percent mark up.
